When I was growing up, my favorite past time was coloring in coloring books. I think I loved it most because my mom would do it with me, she loved it. If it wasn't so dorky I'd do it now, at 31.
Anyway, I had the big giant box of crayons, but of course they were GENERIC crayons from Jewel or something. I would do a dark outline of the shape to be colored and then a super light shading on the inside. Very nice.
I didn't like really DETAILED pictures to color (like the barbie coloring books) I mostly liked big, basic shapes. DOG AND BALL...FISH IN FISHBOWL.
